Remove `cycle_fatal` query modifier

This removes the `cycle_fatal` query modifier as it has no effect on its current users.

The default `CycleErrorHandling::Error` mode does the same as `cycle_fatal` when the default impl of `FromCycleError` is used. The return types of queries using `cycle_fatal` however have no specialized `FromCycleError` impl.
